Options :

A : Least common mechanism

B : Open design

C : Least privilege

D : Least access

Answer: B

Question 2

The Domain NAme System translates domain names, significantly bits of text to IP addresses needed for network communications . The DNS protocol is also a regular DDOs enhancer as it is likely for an attacker to impersonate the IP address of a target in a DNS request , this triggering the DNS server to send unwanted traffic to the target. What other protocols are prone to amplification.

Options :

A :

TCP /IP

B : NTP Network Time Protocol

C : S7 Signifing protocol

D : ARP

Answer: B

Question 3

Confidentiality based on the __________ of data, is meant to provide a way to control the extent to which an adversary can make inferences about users’ sensitive information

Options :

A : Encryption

B : Coding

C : Cryptography

D : Obfuscation

Answer: D

Question 4

Capturing the MAC layer is doable but needs an explicit configuration. Capturing the MAC layer is mandatory to identify attacks like ARP poisoning. For the definite categories of industrial control networks that execute right on top of the Ethernet layer, capturing traffic involves adding a node and could change the real-time conventions. Understanding the information available in the MAC layer requires what?.

Options :

A : The configuration of the network segment to which the collection network interface is attached.

B : Understanding of network architecture.

C : Design configuration of the whole network interface

D : Network configuration in promiscuous mode.

Answer: A

Question 5

Malware essentially Codifies the malicious activities intended by an attacker and can be analyzed using the Cyber Kill Chain Model which represents ( iterations of ) steps typically involved in a cybersttack. What is the first step in the Cyber Kill Chain Model that Cyber Attackers Follow ?

Options :

A : Establishing a command-and-control channel for attackers to remotely commander the victims system

B : Reconnaissance is the 1st step where an attacker identifies or attracts the potential targets by scanning

C : Exploiting a vunerability and executing malicious code on the victims system

D : The 1st Step is to gain access to the targets by sending crafted input to trigger a vunerability
